Often called a manual starter, motor-automatic, or engine protection circuit breaker, this device functions as both a protective switch and a motor starter. It provides overload and short-circuit protection with a magnetic trip unit specifically calibrated to allow for the high inrush currents experienced during motor startup – up to 18 times the nominal current – preventing nuisance tripping. This ensures reliable motor control and protection.
NQ3-5,5P 2,5A 220B is a versatile device functioning as a motor starter, motor protection circuit breaker, and manual motor controller. This compact unit combines the functions of a traditional circuit breaker with motor starting and stopping capabilities. Featuring a magnetic trip unit calibrated for 18x nominal current, it provides robust short-circuit protection for motors up to 5.5kW, offering reliable performance and simplified installation in a variety of applications.
